Chapter 2-Conference Profiles

For instance, an SVC endpoint might want to receive three video streams at different frame rates and resolutions, and create a conference layout with the received video streams. Each SVC-enabled endpoint sends encoded SVC bit streams to the MCU to relay to the other SVC-enabled endpoints in the conference.

The endpoints encode the video in multiple resolutions and decodes the multiple video input streams.

For example:

RealPresence mobile client (2) will transmit two resolutions; one that is suited for RealPresence Desktop client (3) and a second that is suited for two other endpoints: RealPresence Desktop client (4) and (1).

RealPresence Desktop client (1) transmits two resolutions; one that is suited for RealPresence Mobile client (2) and a second that is suited for RealPresence Desktop client (4).

The MCU determines which of the incoming resolutions to send to each endpoint. It does not perform any SVC encoding and decoding, or any transcoding of the video streams. The RealPresence Collaboration Server functions as the multipoint media relay to the endpoints. For voice activated selection of the video streams, the RealPresence Collaboration Server determines which of the incoming bit streams to send to each endpoint.

Advantages of SVC Conferencing

SVC increases the scalability of video networks and enables mass desktop video deployments. Some of the advantages of SVC conferencing are:

•Offers high-resolution video conferencing with low end-to-end latency, improved error resiliency and higher system capacities.

•Allows the SVC-enabled video endpoints to manage display layouts, supporting multiple line rates, resolutions and frame rates.

•The RealPresence Collaboration Server functions as a media relay server providing low cost production benefits. The RealPresence Collaboration Server reduces bandwidth usage by only selecting the necessary video stream to be sent to the endpoints.

Guidelines

•SVC conferences are supported only with the following:

—RMX systems with MPMx card

—CP Licensing

—SIP over UDP signaling

—SIP over TLS Signaling

—Polycom SVC-enabled endpoints (Polycom® RealPresence® Desktop, Polycom® RealPresence® Mobile)

—Ad Hoc conferencing via Meeting Rooms and ongoing conferences

•SVC Only conferences can run on the same MCU as AVC Only conferences.

•All the endpoints participating in a single SVC Only conference must be connected to the same media card and cannot be handled by different media cards as the SVC media streams cannot be shared between them.

•End-to-end latency on a local network (same site), is around 200mSec to ensure AV sync (also known as Lip-sync).

•Dial-out is not available in SVC Only conference.
